Medical Implant (), comprising The implant can be covered with newly created bile duct epithelium, thereby creating a new bile duct from body cells. The implant can be removed after completion of creation of the new bile duct. So, the implant as suitable as a temporary implant. The implant can be used for surgery, such as surgery of gall bladder, bile duct and/or liver, e.g. gall bladder removal, hepatobiliary malignancy surgery or liver transplantation. The implant can particularly be used for repairing or regeneration of bile duct. Further fields of use are the use as esophagus implant or urether implant.

The invention concerns the use of water-soluble polysaccharide derivatives as dispersing agents for mineral binder suspensions. A partially hydrolyzed cellulose containing carboxyl groups and optionally hydroxyalkyl and/or sulfate groups and/or a partially hydrolyzed amylose-rich starch which also has sulfoalkyl groups with 1 to 4 carbon atoms is used as the polysaccharide derivative. These polysaccharide derivatives have a low viscosity and an excellent plasticizing effect in mineral binder suspensions, especially in those based on cement, lime and/or gypsum.

A method of producing a cellueose ether that is predominantly substituted in the C2 position of the anhydroglucose unit of the cellulose is described. The regioselectively substituted saccharide ester produced according to the method of the present invention is selected from the group consisting of oligo-saccharide ester and polysaccharide ester, having a partial average degree of substitution (AS) at the C2 position of its anhydroglucose unit of at least 90% relative to the total AS. Also described is a blood plasma expander comprising the regioselectively substituted ester.

Method of producing regioselectively substituted esters of oligo- and polysaccharides

A regioselectively substituted member selected from the group consisting of oligo-saccharide ester and polysaccharide ester is disclosed. The ester has a partial average degree of substitution AS at the C2 position of its anhydroglucose unit of at least 90% relative to the total AS. Also disclosed is a method of producing the regioselectively substituted ester. The method entails reacting in the presence of a catalyst a dissolved or a highly swollen oligo-saccharide or polysaccharide with an esterification reagent.
